Description

DETAILED DESCRIPTION OF THE INVENTION <Technical Field> The present invention relates to a character editing device such as a word processor, and more particularly to a character editing device useful when editing long texts such as papers.

<Summary of the Invention> The present invention provides means for storing the line end level when setting the line end in a paragraph section of a text, and specifying the range of line end levels of the text to be output when outputting the text. , means for displaying or printing out only characters within the line end level range of the text to be output is provided.

<Background of the Invention> When inputting a long text such as a paper using a character editing device, there are usually a large number of paragraphs and each paragraph usually has multiple indentation positions. However, when the amount of text increases, it becomes difficult for character editing devices that use display devices such as CRTs, which can only display a few dozen lines on a single screen, to grasp the whole picture, and it is difficult to understand each detail. You won't be able to pay attention.

<Object of the invention> The object of the invention is to provide a character editing device that can display or print out only the part desired by the operator by managing the level of the line end of each sentence starting with a line break. It is about providing.

<Structure of the invention> FIG. 1 is a block diagram of the present invention.

The memory 30 for storing input data is composed of a text storage means M1 and an indent position storage means M2, and the text storage means M1 is connected to the text data input means 3.
The indent position storage means M2 stores the text data input from 1, and the indent position input means 3
The indent position input from 2 is stored. Note that the indent position indicates the line end of a sentence, but if this indent position information is expressed by a control code, the sentence data and indent position information may be stored together in the memory 30. It is possible. Each piece of indentation position information has a level corresponding to the distance from the left end position of the text. The int level determining means 33 classifies this indent position information into levels based on the distance from the left end position of the sentence. The indent level instructing means 34 instructs the indent level of the text to be output on a display or the like. The comparison means 35 compares the indentation level instructed by the indentation level instruction means 34 and each piece of indentation position information classified into levels by the indentation level determination means 33, so that the level of the latter indentation position information is equal to the indentation level of the former. A signal for outputting text data that is the same as or included in is input to the text data output means 36. When the text data output means 36 receives a signal from the comparison means 35, it reads out the text data at the address of the text storage means M1 designated at that time and outputs it to a display or the like.

<Operation> As text data and indent position information are inputted from the text data input means 31 and the indent position input means 32, the text data is continuously stored in the text storage means M1, and the indent position storage means M2 stores the text data continuously. Indentation position information is sequentially stored as information indicating the line end. At this time, the text data and indent position information stored in each storage means are naturally displayed on the display. If you want to display or print out only the items or only the text excluding the items from the text displayed on the display,
The indentation level of the text is designated by an indentation level designation means 34. When this indentation level is designated in the output mode, the designated indentation level is guided to one input of the comparison means 35. On the other hand, the data in the sentence storage means M1 and the indentation position storage means M2 are read out sequentially from the beginning, and when the indentation position information is read out in the indentation level determination means 33, the indentation position information is determined from the left end position of the sentence. Determine what level you are based on distance. The determination result is led to the other input of the comparison means 35. The comparison means 35 determines that the text data should be output when the indentation level determined by the indentation level determination means 33 matches the indentation level designated by the indentation level designation means 34 or is included within the designated indentation level. The signal is input to the text data output means 36. When the text data output means 36 receives the signal, it outputs the data of the address of the text storage means M1 specified at that time to a display device or the like.

<Effects of the Invention> By configuring as described above, according to the present invention, even if the text is long and there are many paragraphs with different indentation positions, the text can be read within the specified line end level. You will be able to display or print out only the characters in . For this reason, for example, it is possible to display or print out only the items, or to display papers with a large number of pages in a top-down manner.
It is possible to print out medium items, small items, and main text in that order, as well as create dedicated pages such as indexes and tables of contents, making it possible to edit long texts to make them very easy to read. can.

<Embodiment> (a) Configuration of this embodiment FIG. 2 is an overall configuration diagram of a word processor that is an embodiment of the present invention.

The CPU 1 that controls the entire system includes a CRT 2, a floppy disk 3 that constitutes an external storage device, a printer 4 that constitutes a print output means, a keyboard 5 that inputs sentences, a kana-kanji conversion dictionary 6 that consists of ROM, and a keyboard. A text buffer 7 stores the characters and kanji converted into kanji strings input from 5, an output buffer 8 stores the data stored in the text buffer 7 edited for output, and the following register groups (counters, pointers, ) are connected.

[Indent output level specification register 10] Specifies the upper level of the line end (indentation) of the text to be output in the text output mode.

[Indent output level specification register 11] Specifies the lower level of indentation of the text to be output in the text output mode. This indent output level designation register 11 and the indent output level designation register 10 are used to designate the range of indentation levels of sentences to be output. Note that the indentation level referred to here means the depth of the character position in the line direction of a paragraph section, and the deeper the indentation of the paragraph section, the deeper the level becomes correspondingly deeper.

[Indent nesting number counter 12] Stores the indent nesting number of the line at the position where the cursor is located, that is, the position specified by the text buffer pointer described later. That is, the indentation level is divided based on the distance from the left end position of the text. The nesting number is a numerical value representing the depth of the indentation level.

[Sentence buffer output range designation pointer 13] The address of the text buffer 7 corresponding to the beginning position of the text specified as the output range is stored.

[Sentence buffer output range designation pointer 14] The address of the text buffer corresponding to the last character of the text for which the output range has been specified is stored. An output range within the text buffer 7 is designated by this text buffer output range designation pointer 14 and the text buffer output range designation pointer 13.

[Output device specification register 15] Specifies whether the output device is CRT2 or Printer 4. “0” specifies the CRT, and “1” specifies the printer.

[Page output specification register 16] Specifies whether or not to output a page. “1”
Specify page output with .

[Text buffer pointer 17] Points to the character position in the text buffer 7 corresponding to the cursor position.

[Page counter 18] Constructs a counter that indicates which sheet the current cursor position corresponds to.

[Line counter 19] Constructs a counter that indicates which line of paper the current cursor position is on.

[Character counter 20] Constructs a counter that indicates the number of characters from the beginning of the line at the current cursor position.

Note that the text buffer 7 stores not only sentences input from the keyboard 5 but also indentation and indentation end codes, and serves both as character storage means for storing input sentences and indentation position storage means for storing indentation positions. Also keyboard 5
It also has a function key for entering indentation.

(b) Outline explanation of this embodiment An overview of the operation of this embodiment will be explained with reference to FIGS. 3 to 5.

The text output mode is set by pressing a predetermined key when outputting the input text.
FIG. 2 shows the first display screen when the mode is set. Item 1 is an inquiry as to whether or not to specify an output range. If "no" is specified with the cursor, all the contents to be stored in the text buffer 7 are specified as the output range. When “Required” is selected,
The display screen is switched to text content (not shown)
The range is specified by specifying the area using the cursor.

Item 2 inquires about the range of indentation levels of sentences to be output. It is now assumed that a sentence as shown in FIG. 4 is stored in the sentence buffer 7.
The symbols enclosed in a square here are an indent mark (a mark entered at the beginning of a paragraph part of a sentence) and an indent end mark (a mark entered at the end of a sentence). As shown in the figure, the indentation level becomes deeper as it advances in the row direction. For example, the indentation level of the paragraph “This invention is” is 3,
The indentation level of the paragraph section of “1-1 Abstract” is 1
It is. With the indent level set in this way, if the indent level is set from 0 to 3 in item 2 on the display screen shown in FIG. 3, all the sentences shown in FIG. 4 will be output. On the other hand, if the indentation level is specified in the range of 1 to 2, for example, only the text in the hatched area will be output.

Item 3 on the display screen in FIG. 3 inquires whether or not to output the page. If "No" is selected with the cursor, the page will not be output. If "required" is selected, the page will be output. FIG. 5 shows an example of the output when this page output "Key" is selected and the indentation level range is selected from 0 to 2. As shown, the page output is output on the right side.

Item 4 in Figure 3 asks whether the output device should be a CRT or a printer. with cursor
If CRT is selected, output device specification register 1
5 is set to "0", and if a printer is selected, "1" is set to the output device setting register 5.

By performing the above input in the text output mode, it is possible to easily set the output text in units of paragraphs by specifying the output content, especially specifying the range of indentation levels.

(c) Description of operation FIG. 6 is a flowchart showing the operation of the word processor in the text output mode.

When the text output function key is operated and the text output mode is set, step n1 is first executed.
(Hereinafter, step ni will be simply referred to as ni.) The screen shown in FIG. 3 is displayed, and the output range is specified. Next, the register group is set based on the contents input at n2. If item 1 is "no" on the display screen shown in FIG. 3, the start address of the text buffer 7 is set in the text buffer output range specification pointer 13,
is set to the last address. If "required", the addresses of the start position and end position designated by the operator with the cursor on the next screen (not shown) are set in the designated pointers 13 and 14.
The first level of indent specified by item 2 on the display screen of FIG. 3 is set in the indent output level designation register 10, and the next level is set in the indent output level designation register 11. If "No" is selected in item 3, the page output designation register 16 is cleared, and if "Required" is selected, 1 is set in this designation register 16. When “CRT” is selected in item 4, output device specification register 1
5 is set to "0", and when "Printer" is selected, "1" is set.

Furthermore, the start address of the text buffer 7 is set in the text buffer pointer 17, the indentation nesting number counter 12 is cleared, the page counter 18 is set to "1", the line counter 19 is set to "1", and the character counter 20 is set to "1". ” respectively.

Once the register groups are set as described above, output processing is then performed according to the contents of these register groups.
First, the text buffer up process is performed at n4 until the position specified by the text buffer pointer at n3 becomes the start position. As will be described later, in this text buffer up process, the text buffer pointer 17
Up processing is performed. When the content of the text buffer pointer 17 reaches the start position, it is determined in n5 whether that position (current position) has reached the end position. It's not there at first, so move on to n6. In n6 and n7, the contents of the text buffer pointer 17 are the indent output level specification registers 10 and 1.
Determine whether it is within the indentation level specified by 1. If it is within the range, the character in the text buffer specified by the current text buffer pointer 17 is set in the output buffer 8 at n8.
Next, at n9, a text buffer up process is performed, and the process returns to n5 to determine whether the content of the text buffer pointer 17 has exceeded the end position. The above processing is repeated until the content of the text buffer pointer 17 exceeds the end position. Beyond the end position,
At n10, the stored contents of the output buffer 8 are output to the output device set in the output device designation register 15, and the process ends.

FIG. 7 is a detailed flowchart of the text buffer up process.

In this process, first, the contents of the text buffer pointer 17 are incremented at n20. Further, in n21, the line counter 19 is incremented by one, and the number of characters from the beginning of the line is increased. Then, it is determined whether the number of characters in one line is equal to the number of characters from the beginning of the line, that is, the character count (n22). If they are not equal, it is checked in n23 whether the content indicated by the text buffer pointer 17 is an indent code or an indent end code. If an indentation code is indicated, the indentation nesting number counter 12 is incremented by one at n24, and if an indentation end code is indicated, the same counter 12 is decremented by one at n25. As a result, the indent nesting number counter 12 indicates the number of indent nestings in the line where the cursor is currently located, that is, the character position indicated by the text buffer pointer 17.

If the number of characters per line and the character count are equal in n22, the process advances to n26 and the contents of the page output designation register 16 are determined. If it is "0", skip n27 and proceed to n28; if it is "1", the contents of the page counter 18 are transferred to the output buffer 8 at n27.
At n28, the character counter 20 is returned to 1, and at n29, the line counter 19 is incremented by one. Further, at n30, it is determined whether the number of lines on one page is equal to the contents of the line counter 19, and if the contents of the line counter are less than the number of lines on one page, the process skips to n23. Otherwise
The line counter 19 is returned to 1 at n31, the page counter 18 is incremented by one at n32, and the process proceeds to n23.

By the above operation, the text buffer pointer 17
At the same time, counters and the like are updated at the same time.
